Cell Process

At LG Solar, quality-assurance is a top priority, that's why our solar panels are created using the most technologically advanced processes available. Our state-of-the-art manufacturing facilities are designed to produce high quality, high performance cell panels that come ready to perform.


LG Solar Cell Process

Inspection

Each wafer is thoroughly examined and measured to eliminate defects, so only the best-quality wafers are selected.

Wet Etching

Selected wafers then undergo a wet etching process which surfaces are immersed in acidic (multi) and alkaline (mono) solutions to help reduce light reflection.

Diffusion

N-type emitters are formed by loading P-element POCI3 gas into P-type wafers.

AR Coating

These wafers are then coated with an anti-reflective SiNx:H film through a PECVD method using SiH4 & NH3 to dilute reflection and improve passivation.

Metallization

Metallic electrodes are composed to gather activated electrical carriers (electrons and holes) for each cell.


LG Solar Cell Process

Sorting

Cells are finally measured and sorted by efficiency and classified by level of defect, color and electrical characteristics
